Installation
& Start Up
- J-Series adsorbers are shipped empty along with the
required carbon. The adsorber should be connected and all fittings
pressure tested for leaks before the carbon is installed through
the top access hole. After the carbon has been loaded, the unit
should be filled with clean water through the bottom collector,
and allowed to degas for 8-12 hours if possible. Backwashing
the carbon is recommended to remove carbon fines that can cause
excessive pressure drop through the unit. Multiple units are
usually connected in series with testing between the units advised
to determine when the first unit needs to be changed out.

Maintenance
- The only
maintenance J-Series adsorbers requires is the testing
of effluent quality, and checking the operating pressure of
the system. Monitoring the contaminant level into the last unit
in a series arrangement is the recommended safeguard against
having breakthrough in the final outflow. When the concentration
of contaminants in the flow coming out of the lead unit equals
the concentration of the flow into the unit, the unit has reached
its removal capacity and needs to be serviced. The working life
of carbon is dependent upon the type of contaminant in the water
as well as its concentration and the liquid flow rate. A pressure
relief device is advised to prevent damage to the system in
the event of excessive pressure buildup. Backwashing an adsorber
that is operating at an elevated pressure will sometimes provide
a temporary lowering of the pressure drop through the unit.

Servicing
J-Tanks
- Once an adsorber's carbon is saturated by contaminants, the
unit should be taken off line and fresh carbon installed. To
purchase replacement carbon or to arrange for a carbon change
out, please contact our office. When preparing the unit for
servicing, as much water as possible should be drained from
the vessel.
|
| |
Disposal
- If you change the carbon out yourself, please dispose of the
spent carbon in accordance with Federal, State and Local regulations.

Warning!

Wet
activated carbon readily absorbs free oxygen. ANY entry into
carbon vessels requires procedures for confined space entry
and oxygen depletion to be followed!
